About this 1.57ct lab-grown heart diamond

This 1.57ct lab-grown heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG733599633 or 733599633. Listed at 22 retailers as of October 27, 2026, with a 445% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
